Recent organic pollution and its biosensing methods

Rapid economic growth in Japan resulted in serious organic pollution in the 1960s. In contrast, recent organic pollution is caused primarily by phosphorus-based anthropogenic eutrophication, which also induces heavy metal pollution. In the present review, causes of the recent organic pollution are briefly introduced, and our approaches, based on studies of environmental water biosensing methods as tools for estimating the degrees of the recent organic pollution, eutrophication, and heavy metal pollution, are introduced.
